Preheat your oven to 400°F (200°C).
In a small oven-safe skillet, heat the olive oil over medium heat and add the ground turkey, breaking it apart with a spoon.
Season the turkey with sea salt, black pepper, dried oregano, and minced garlic, cooking until the meat is browned and cooked through.
Stir in the cherry tomatoes and fresh spinach, cooking for 2-3 minutes until the tomatoes begin to soften and the spinach wilts.
Use a spoon to create three small wells in the turkey and vegetable mixture.
Carefully crack one egg into each well, ensuring the yolks remain intact.
Sprinkle the crumbled feta cheese evenly over the top of the skillet.
Transfer the skillet to the oven and bake for 8 to 10 minutes, or until the egg whites are fully set but the yolks are still slightly runny.
Remove from the oven and let cool for a minute before serving directly from the skillet.
